Abstract
The invention relates to a glass substrate (1) provided with an electrode comprising at least one metal oxide-based transparent conducting layer (3), characterized in that said layer has an RMS roughness of at least 3 nm, especially of at least 5 nm and/or a mean feature size for this roughness of at least 50 nm.
Claims18
A composite structure, comprising:
- a glass substrate;
- and
- an electrode provided on the glass substrate;
- wherein:
- the electrode comprises at least one metal oxide-based transparent conducting layer;
- a surface of the at least one conducting layer opposite from the glass substrate has an RMS roughness from 3 nm to 30 nm;
- a mean feature size for the roughness of the surface of the at least one conducting layer opposite from the glass substrate is from 200 to 400 nm;
- a surface of the glass substrate on which the electrode is provided has an RMS roughness from 100 to 5,000 nm;
- and
- a mean feature size for the roughness of the surface of the glass substrate on which the electrode is provided is from 10 to 50 μm.
